| Abstract: | ~(57)Fe M?ssbauer spectroscopic study was carried out on the organic rich sedimentary samples collected at different depth intervals from newly drilled test well Chinnewala Tibba-1(CT-1) located in Jaisalmer Petroliferous basin India. It is found that iron is mainly distributed in high spin Fe3tand Fe2tstate in clay minerals. The plot of Fe2t/(Fe2tt Fe3t) indicates the presence of poor redox conditions in the samples.Results obtained are also compared with those already reported in the literature. This comparison shows that there may exist a correlation between prospecting of the basin, the redox environment in sediments and the nature of iron bearing minerals distributed in the sedimentary sequence. |
